COMBINATION ROLLER-BOLSTER AND STAKE-POCKET.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed May 16, 1919. Serial No. 297,642.

' ti-on Roller-Bolsters and Stake-Pockets; and

I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany .ing drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to combined bolsters and stake pockets and it is particularly applicable for use in vehicles adapted to trans port lumber and the like.

One of the objects of the invention to provide means whereby the load may be expeditiously discharged from the vehicle, there being stake pockets provided and. supported thereby, the construction being of simplified design and capable of easy assemlage.

In the drawings,

Figure I is a perspective view of a vehicle frame to which my invention is attached.

Fig. II is a fragmentary perspective view of one of the bolsters.

Fig. III is a sectional view through one end of the bolster and stake pocket, and

Fig. IV is a perspective view of a stake pocket and one end of the bolster showing the means by which the stake pocket engages the bolster sills.

The vehicle body is illustrated as consisting of side sills 1 and 2 and end sills 3 to provide a substantially rectangular frame in any well known manner. Supported upon the side sills are bolsters, each of which is shown as consisting of channel irons indicated by reference numerals a and 5 and having their flanges disposed in opposite directions. The spaced bolster sills 4 and 5 are connected at their ends by hearing plates 6, each of which is provided with oppositely disposed projections 7 and 8 which rest upon the top flanges of the channels 4: and 5, the major portion of the plate projecting down between the webs of said channels and each bearing plate is provided with an opening 9 to receive a trunnion 10 of a roller 11 which projects slightly above the top flanges of the sills 4L and 5. The rollers are pro vided with longitudinal recesses or openings 12 and the bearing plates 6 with an opening 13 so that a locking pin 14 may be inserted through the opening 13 and through one of the openings 12 to hold the rollers rigid with respect to the members 4L and 5 when the load is being transported. The locking of the rollers with respect to the bolster channels eliminates liability of the load shifting longitudinally while in, transit.

On the respective ends of the bolsters are provided stake pockets, these being formed by providing a strip with inwardly bent ends extending around the ends of the channels and around the bearing member 6, the ends of the strip engaging with kerfs or notches 16 and 17 in the top and bottom flanges respectively of the bolster sills d and 5 and thereby providing stake pockets or loops 18 and 19, as best seen in Fig. IV. The strips are secured rigidly with respect to the bearings and the bolsters by fasteningdevices 20 and 21 which may consist of bolts or other suitable means. I11 order that the stakes may be held against accidental displacement I have provided resilient en gaging means shown as springs 22 and 23, each'of which is secured to one end of a projection 7 or 8 on the bearings 6. In Fig. II it will be observed that the flat spring 22 is fastened to the projection 7 by a fastening member 24: while a corresponding flat spring 23 is fastened to the projection 8 by a fastening device 25, thereby providing a stake pocket having one spring wall and a rigid wall to insure that the stakes 26 will be held in their respective pockets.

The bolsters are arranged suitable distances apart so that the load will be ellciently supported upon the rollers which cannot turn unless the pins 14: are withdrawn. Vhen the pins 14 are withdrawn, however, the entire load may be shifted lon ,Qitudinally to discharge from the vehicle. The free ends of the springs 22 and 23 normally incline slightly toward the respective edges of the stake pockets and therefore provide tapered pockets to receive the stakes and thereby bind them in place.

It will be apparent from the foregoing that the device is simple in construction,

that it may be readily applied to an ordi nary vehicle and that it is well adapted to serve the purpose for which it is intended.

What I claim and desire to secure by Letters-Patent is:

1. A combined bolster and stake pocket, comprising a bolster, and a stake pocket member extending across and around the end of the bolster to form stake-receiving loops on opposite sides of the bolster.

2. A combined bolster and stake pocket comprising a bolster, and a stake pocket member secured to the end of the bolster, the ends of the member constituting stake pockets located on opposite sides of the bolster.

3. In a combined bolster and stake pocket,

' a bolster comprising channels spaced apart and having their flanges disposed in opposite directions, roller bearing members connecting the ends of the channels, a roller journaled in the bearing members and between the channels, and a stake pocket consisting of a strip fastened to the end of the bolster and having its ends bent back upon the main portion thereof, to form loops, the ends of the strips engaging the bolster.

4. A combined bolster and stake pocket comprising spaced sills, bearings connecting the ends ofthe sills, a roller supported by the bearings and between the sills, a stake pocket member fastened to each end of the bolster and having oppositely disposed loops to receive stakes, and depending springs carried by the bearing member and within the stake pocket.

A combined bolster and stake pocket comprising a bolster and a stake pocket member carried by the bolster, having oppositely disposed loops and fiat springs within the pocket and extending longitudinally thereof.

6. A combined bolster and stake pocket comprising a bolster consisting of spaced sills of channel form with the flanges of the channel extending in opposite directions, 4F

bearing members connecting the ends of the channels, said bearing members having oppositely disposed projections resting upon and secured to the top flanges of the chunnels, and a strip looped around the end of the bearing members and engaging the flanges of the channels, the ends of the loop formed by the strip consisting of stake pockets.

7. A combined bolster and stake pocket comprising a bolster consisting of spaced sills of channel form with the flanges of the channel extending in opposite directions, bearing members connecting the ends of the channels, and having oppositely disposed projections, a strip looped around the end of the bearing members and engaging the flanges of the channels, the ends of the loop formed by the strip consisting of stake pockets, and stake engaging springs carried by the oppositely disposed projections on the bearing members and positioned within the stake pockets.

8. A combined bolster and stake pocket comprising a bolster, a stake pocket member carried by each end of the bolster, and having oppositely disposed loops and stake engaging springs within the pockets.

In testimony whereof I afiix my signature.

RALPH E. BYRNE.
